Thickness Selection Guide
The 3 mil thickness represents heavy-duty protection in the poly bag spectrum. This gauge is recommended for items with sharp edges, heavy products, or applications requiring extended storage protection. For lighter-duty applications like dust covers or temporary storage, consider 1.5 or 2 mil options. For extreme protection requirements, 4 or 6 mil bags provide maximum durability.
